For some reason when i get in the car afte letting it sit for more than 4hrs or so... the Parking brake and Battery light stay on while i drive. The lights will eventually go off after 15 mins or so of driving. Any idea what this could be? I just replaced the battery, think the brake would be brake fluid?

Have you checked its level? Sensor operation?

Typically this is a low voltage condition... like a an alternator failure. On the G50 Q45 the ABS light and brake light double as low voltage indicators.

That's correct, those two lights being on at the same time mean you have a low voltage. (It has nothing to do with the brakes). You're in trouble if you don't solve the problem soon... If you just replaced the battery, I hope it was a new battery (sounds silly to say this but some ppl buy used batteries, lol).

99% probability that your alternator is failing. Consider changing the alternator belt and this might solve it, but I doubt it. Also, the fact that it seems to drain a little over a few hours means that you might have a power leak when the car is off. (light bulb ususally).

The reason it goes off after you run the car for awhile is further sign that the battery or alternator is failing. Once the battery finally builds up enough voltage, the lights will go off. KEEP IN MIND that hard driving (flooring it everywhere like me) will draw alot of power and will kill a dying alternator/battery. So take it easy till ya get it sorted out.
